Technical Architect

The Job

Own and drive the end-to-end application security strategy, including design reviews, threat modelling, and secure SDLC integration across engineering teams.

Lead an AI-augmented red team program — designing adversarial scenarios that simulate AI-generated attacks (LLM prompt injection, adversarial ML, AI-assisted phishing, synthetic exploit generation) and translating findings into hardening roadmaps.

Architect and maintain an AI-driven threat assessment framework to continuously identify, prioritize, and remediate vulnerabilities across web, mobile, API, and cloud-native applications.

Define and govern counter measures against AI-generated attacks, including detection pipelines, model-aware WAF policies, and runtime application self-protection (RASP) strategies.

Perform and oversee advanced application penetration testing and dynamic/static analysis (DAST/SAST) with a focus on high-complexity environments.

Collaborate with product, DevOps, IT and platform engineering to embed security guardrails at every stage of CI/CD pipelines — shift-left and shift-everywhere.

Mentor and guide a team of security engineers; establish technical standards, playbooks, and review processes.

Stay ahead of emerging threat intelligence, particularly adversarial AI research, and adapt defensive strategies accordingly.

Lead collaborative Purple Team exercises to the next level, leveraging AI to provide a wider coverage against blue team defenses, with real-time feedback loops to identify detection gaps.

Facilitate structured debrief sessions after each exercise, driving measurable improvements in SIEM rules, EDR coverage, alert fidelity, and incident response runbooks.

Qualifications & Skills required

Education & Experience:

Bachelor’s degree in computer science, Information Security, or a related field.

Minimum of 10+ years of experience in Application Security is a must.

Proven track record owning application security programs in a complex, multi-stack enterprise environment.

Deep, hands-on experience leveraging AI/ML tooling both offensively (red teaming) and defensively (anomaly detection, AI-powered SIEM correlation).

Demonstrated ability to design and execute AI-specific attack simulations — prompt injection, data poisoning, model inversion — and build mitigations.

Strong understanding of modern application stacks: containerized microservices, serverless, GraphQL APIs, OAuth 2.0 / OIDC flows.

Experience integrating security tooling (SAST, DAST, SCA, secrets scanning) into CI/CD pipelines.

Lead collaborative Purple Team exercises with AI.

Work closely with the SOC, threat intelligence, and incident response teams to ensure purple team findings directly feed into defensive improvements.

Evaluate and deploy purple team platforms (e.g., Safe Breach or custom automation) to scale exercise frequency and reporting.

Guide and upskill red and blue team members in purple teaming methodology — building a culture of continuous adversarial validation.

Technical Skills:

Understanding of threat intelligence sources and risk management frameworks (e.g., NIST, CVSS).

Strong knowledge of network and application security, as well as common vulnerabilities and attack vectors.

Strong knowledge of OWASP Top 10 and secure coding practices

Experience with SAST, DAST, IAST, and software composition analysis (SCA)

Secure SDLC and threat modeling (e.g., STRIDE, PASTA)

Knowledge of LLM attack vectors · Adversarial ML · AI red teaming · Prompt injection

Experience and hands on with Purple Teaming, ATT&CK mapping · VECTR / Picus · Debrief facilitation · Detection tuning.

Have worked on Zero trust · API gateway security · Cloud-native · Microservices
